Chills are the sensation of feeling cold.
They often occur alongside a fever, which is when a person’s body temperature is higher than normal.
However, a person can also experience chills without a fever, and there can be many different reasons for this.
Potential causes include:
- Being cold
- Having hypothyroidism, which causes more sensitivity to cold
- Infection
- Doing intensive exercises in the cold
- Having anemia
When to see a doctor
If a person experiences chills because they are in a cold climate or are experiencing the early signs of a mild fever, they probably will not need to see a doctor.
However, if a person experiences other symptoms, or they frequently feel cold even when it is warm, and they are wearing many layers, they may have an underlying health issue. A doctor can help diagnose what this is and suggest appropriate treatment.
